Restore archived tasks, fix dashboard scroll-reset, bind ornith, add Playwright smoke test

- **Restore 82 completed tasks** from tasks/complete/ back to tasks/ top
  level (all <7 days old per the cleanup policy; premature bulk archive
  was fixed).
- **Dashboard: fix scroll-reset on auto-refresh** — renderBoard rebuilds
  the board via innerHTML every 2s, destroying each column-body's
  scrollTop. Now snapshots column-body scrollTop + board.scrollLeft +
  view.scrollTop before rebuild and restores after (matched by
  PHASE_GROUPS index).
- **Dashboard UI additions** (pre-existing unstaged work): approval
  section cards, transition buttons, inline artifact editor (textarea for
  writing missing SPEC/VERDICT/etc from the detail modal).
- **Bind ornith as Implement model** — config.md: Model explicit to
  omlx/Ornith-1.0-35B-4bit-mlx, context window 32768. Interactive
  autopilot already used ornith via opencode default; now explicit.
- **Fix cleanup stub** — automaton-cleanup.sh had a stale --project arg
  pointing at a pytest temp dir (test isolation leak). Rewired to point
  at ~/.automaton.
- **Fix plist-isolation test** — test asserted host plist doesn't exist,
  but a real install creates it. Now snapshots mtime before run, asserts
  unchanged after (only a write during the test counts as bleed).
- **New Playwright smoke test** (tests/test_dashboard_ui.py) — 2 tests:
  board renders tasks, column scroll survives auto-refresh tick.
  Verified the test fails without the scroll fix (scrollTop resets to 0).
  Skipped via importorskip when playwright is absent (main CI stays
  green).
- **Clarify SI loop scope in README** — new-project onboarding section
  documents the framework-scoped self-improvement loop and options
  (leave/pause/create project loop).
- **CHANGELOG** documents all changes including the known model-divergence
  gap (mde tasks marked complete but per-role model binding was never
  implemented).

+# IMPLEMENTATION: move-completed-tasks-to-complete-folder
+
+## Summary
+
+When `--transition complete` is called, the task directory is now moved from `tasks/<name>/` to `tasks/complete/<name>/`. The `_task_dir` function has a fallback to find completed tasks. `--list` and `--audit` exclude completed tasks.
+
+## Changes
+
+### R1 -- `_task_dir` fallback (scripts/status.py:236-249)
+
+Added a fallback check: if `tasks/<name>/` doesn't exist, check `tasks/complete/<name>/`. This ensures `--task <name>`, `--transition`, `--approve`, and all other commands that call `_task_dir` still find completed tasks.
+
+### R2 -- `cmd_transition` moves task directory (scripts/status.py:601-610)
+
+After `_write_state(task_path, target)`, if `target == "complete"`, the function:
+1. Computes the tasks root directory (`task_path.parent`)
+2. Creates `tasks/complete/` if it doesn't exist
+3. Renames `task_path` to `tasks/complete/<name>/`
+4. Refuses if a completed task with the same name already exists
+
+### R3 -- `_all_task_dirs` unchanged
+
+`_all_task_dirs` does NOT scan `tasks/complete/`. Only `--task <name>` with fallback can find completed tasks.
+
+### R4 -- Tests
+
+`tests/test_move_completed.py`: 9 tests across 3 classes:
+- `TestTaskDirFallback` (3 tests): regular path, completed fallback, regular preference
+- `TestAllTaskDirsExcludesCompleted` (1 test): completed tasks excluded from listing
+- `TestCompleteMovesDir` (5 tests): move, dir creation, create-task refusal, transition refusal, state read after move
+
+### R5 -- Documentation
+
+- `CHANGELOG.md`: task 9 entry
+
+## Verification
+
+- `python3 -m py_compile scripts/status.py` -- OK
+- `python3 -m pytest tests/test_move_completed.py -v` -- 9 passed
+- `python3 -m pytest tests/ -q` -- 433 passed (424 + 9 new)
